Application Parameters
There are parameters that apply to every Ice Bear unit installation. Below is a list of installation
constraints that need to be strictly followed to ensure proper operation and reliability of the Ice Bear unit.
Installation constraints for the Ice Bear unit:
Item Specification
Line Set Sizing
Ice-Coil™ supply line = 1/2”
Ice-Coil return line = 7/8”
(Both lines must be insulated.)
Maximum overall
length (to Ice-Coil)
150 ft including vertical head (maximum 20 fittings)
Maximum vertical head
Ice-Coil supply line
35 ft
Maximum vertical head
Ice-Coil below Ice Bear
unit
20 ft
Maximum fittings per
line (supply & return)
20
Minimum insulation
wall thickness
1/2” or minimum required by local code, whichever is greater.
Isolation valves with
service ports
Isolation valves with service ports must be field installed in the Ice-
Coil supply and return lines, as close as possible to the coil.
Sight Glasses
Install sight glasses in the Ice-Coil supply and return lines, as close
to the Ice Bear unit as possible.
Any deviations from the above parameters require review by Ice Energy’s Technology department.
NOTE:
When applying an Ice Bear 30 unit to a heat pump, the Ice Bear unit must have a dedicated
(redundant) Ice-Coil.
